Let me start with that first link, because it's a doozy. You said "mental illness have increased over time", but the paper said that _certain_ mental illnesses increased in _young_ Americans. Off that bat, that representation of the facts is not right. But even worse, you are applying this to a discussion about belligerence towards police, and the _types_ of mental illness mentioned by the paper starts with, that's right, depression.

I do not envision depression making a person more likely to lash out in a police confrontation. In the comment chain here, this is also presented in a the-sky-is-falling kind of narrative about the danger of the streets in the US. I'm going to be honest, this is upsetting to me. I was willing to listen to where you're coming from. Is this how police think? I don't like that thought.
